zenml
One AI platform for pipelines and agents, from development to production.
Write workflows in Python that run on any infrastructure backend and integrate your existing ML tools.
ZenML is an open-source framework designed for ML and AI engineers to build and operationalize workflows ranging from classical models to complex agentic loops. It provides infrastructure abstraction, automated containerization, and a client-server architecture with a built-in dashboard.
What it is
It lets you write Python workflows that embed any logic—like model training or agentic loops—and run them across different infrastructure backends. It operationalizes your code by tracking metrics, logs, and metadata while integrating tools like MLflow, Langgraph, and GCP Vertex.
Who it's for
It suits ML and AI engineers working in company settings who need to standardize and operationalize their AI workflows across varying infrastructure. It does not suit hobbyists or solo developers looking for simple script execution without the overhead of pipeline orchestration.
Key features
Pipeline Orchestration
Write Pythonic workflows that execute across any infrastructure backend.
MCP Server Integration
Query pipelines, analyze runs, and trigger deployments using natural language.
Infrastructure Abstraction
Automatically containerize code and hide backend infrastructure complexity.
Tool Integration
Connect existing systems like MLflow, Langgraph, Langfuse, and SageMaker.

Our honest verdict
What's great
- Orchestrates both classical ML workflows and modern AI agent loops in one framework.
- Native Model Context Protocol (MCP) server allows natural language pipeline management.
- Integrates smoothly with established experiment trackers like MLflow and Weights & Biases.
- Extensive example library covering RAG pipelines, fine-tuning, and agent comparisons.
Where it falls short
- Requires setting up and running a client-server architecture for production usage.
- Adds architectural abstraction overhead that may feel excessive for simple scripting tasks.
- Requires ongoing maintenance of backend stack integrations and infrastructure state.
Pricing & license

FAQ
Do I need to rewrite my existing models or agents to use ZenML?
No. You simply wrap your existing code in a decorator step while keeping your preferred libraries like scikit-learn, PyTorch, or LangGraph.
How is ZenML different from observability tools like LangSmith or Langfuse?
While those tools focus on LLM observability, ZenML orchestrates the full MLOps lifecycle for your entire AI stack, managing both classical ML and agents.
